And also, what about pH's alter ego pOH?

可是，pH到底是什么？

The pOH in this case is 10.5.

另方面，比如说氨这碱。

And finally, you learned about some cool mathematical connections between pH and pOH.

比如柠檬，电离完全。

Just as we can calculate the pH of a substance from it's hydrogen ion concentration, we can calculate the pOH.

就是同pH值环境中会显现同颜色的化学物质。

But, if the poor creature has lost so much skin from off her back. Poh, poh! That is just one of Tim's large stories.

但是，如果可怜的家伙背上脱了很多皮。咳，咳！那只是蒂姆编的个故事。
